To all whom, it iii-rig concern:

Be it known that 1, CHARLES H. HAoxET'r, a citizen of the U nitcd Statesof America, and a resident of Waterloo, Blackhawlc county, iowa, haveinvented certain new and useful improvements in Centrifugal Liquid-Separaters, of which the following is a specification.

My invention relates to improvements in centrifugal liquid-separators;and the object of my i n1pr.:. vement is to provide an exittube for thenewly-senarated lighterconstitucnt of the liquid which shall be socapable of adjustment that its inner end may be brought nearer to orfarther away from the axis-of the separator-bowl, as desired, while theenter or true exit end of said tube re mains fixed in one position. Thisobject i ha e accomplished by the means which are hereinafterdescriliied and claimed and which are illustrated in the accompanyingdrawings, in whiclr- I Figure l is a vertical section of a separatorbowlalong the line of its axis containing my improved exit tube for thelighter separated constituent of the liquid. Fig. 2 is a detail vieu ofsaid tube, and Fig. 3 is a horizontal section of said bowl along theline w a of Fig.1

Similar reference characters refer to similar parts throughout theseveral views. l have depicted a sqaarator-bowl g of a familiar type,having a cover whose ringshaped top f has a central. opening for thereception'oi' a clamping-shaft 7s. The latter an expanded body at thetop containing a chamber communicating by means of an opening in withthe interior of the bowl for the entrance to the bowl of the liquid tobe separated. The lower end of said shaft 7c is provided with thread tofit into a threaded opening in the enter oi the upper surface of thebottom of the bowl. a is an exit for the heavier separated constituentof the liquid.

1 have shown a liner of a simple type within said bowl composed ofstandardsc 0, connect ing circular top and bottom plates Z) and 72,respectively. The top plate I) has an open-- inc near the usual .,outerdividing-point of the ligditor and heavier constituents of the liquid,and in this opening a vertical tube a is fixed in such a manner that itsupper end projects above said plate and extends into and to the top of aregistering opening in the ring on the cover of the separator-bowl. The

lower end of said exit-tube a extends downwardly into the interior ofthe bowl, and a short distance below the plate 5 said tube is cut awayin such a manner along a plane passing vertically along its axis as toleave the vertical open side of the remaining half directed toward theaxis of the separator-bowl and parallel therewith. This tube is openthroughout its extent and ailords means of unobstructed communicationbetween the interior and exterior of the bowl for the exit of theseparated lighter constituent of the liquid.

in order to shii t the lower end of the tube a toward the axis of thebowl, i have placed means tlicrcfor adjacent to the outer portion of thelower end of its trough-shaped part,- described as follows: On astandard c adjacentto the tube a is mounted anintcriorlythreadedbearing-lug d, with axis at right angles to the lower end of said tube.Within this bearing works a screw (2, having a slot across the face ofits outer end, whereby it may be turned by the use oi a screw-driver.The inner end of sai screw e impinges against the outer side of thelower end of the trough oi said tube a and. when said screw is turned inone direction pushes inward the elastic trough to a point nearer theaxis of W R T6 WlLBUR W.

the separator-bowl and when turned back allm s the lower end of saidtrough to spring back to its former position to any required degreewithin its compass oi movement. When. the lower end of the trough of thetube a pushed inward nearer the axis of the bowl, it is in a position toskim a liquid such as milk where the 'milk. contains a high degree orpro iiortiiim oi cream, and when the tube allowed to move to anadjustment farther out it is in. position to skim when the milkcootziiins a less proportion oi cream.

1" tteniion is particularly called to the fact that the upper end andproper exit of the tube a is in a :iixcd position within theseparatorbowl, being rigidly connected to the upper lower end oi words,the SllJlbl ll'? oi the lot-vet of the tube, While permitting adjustmentto skim milk according to the relative proportion. of cream containedtherein, doesnot alter the direction of delivery or the position of theexit.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In a eentrifu al liquid-separator bowl, an exit-tube for the lighterseparated constituent of the liquid Whose upper end is in a fixedposition relative to the axis of the bowl, and whose lower end isadjustable toward and from said axis, and means for adjusting the lowerend of said tube toward and away from said axis.

2. In a centrifu al liquid-separator bowl, an exit-tube for tie lighterseparated constituent of the liquid Whose upper end is in a fixedposition relative to the axis of the bowl, the lower end of said tubebeing opened into the shape of a trough on the side nearest said axisand adjustable relatively toward and from said axis, a liner Within saidbowl, a lug having an interiorly-threaded bearing af- 2 fixed to saidliner, a screw in said bearin adapted to contact with the lower end ofsaid exit-tube and adjust it to a greater or less distance from the axisof said bowl.
